A very specific question but i'm considering the revo remap at JKM (portsmouth) to take my pd130 to 170bhp and 280lb ft torque quoted online for £350. My mate had his mk4 golf gti anniversary done there with full exhaust system and hes had no problems and it seems to make a big difference! Just wondering if anyone here has had their mk4 done and how they've found it? ta, Rach
